Most yield I can get from 1 plant 225 watt hps

Co2 and perfect conditions I say 4 oz

4-6oz is what you should get.

I average about 5oz in a 5 gallon pot with a 250hps at 75-81 degrees, no co2 but other than that perfect conditions.

yes 4 oz is pretty easy and quite possible to get up to 6 oz

just remember that its only the top buds that is close to the light that will be top quality, lower bud sites, specially with a 250W wont be that dens or mature and IMO more suitable for oil/hash making so maybe 2-3 Oz of top buds and 1-2 oz of flimsy buds ..

keep the plant low and bushy, look in to Scrog maybe, seen Ppl get good results with one plant and low Watt light ..

Dunno never heard of a 225w HPS.

lol, me nighter, but I have heard about typos

Well the light is gonna be 250 watts the last 3-4 weeks of flower before that 175.... I have no scrog sceen, it's more of a net trellis thats made of string. The only thing I can do with this trellis is tie the plant down I guess ???

A million dollars worth!
